Description
When a system receives digits from station, CO line, the dialed digits are converted
according to the Digit Conversion Table before the Numbering Plan is checked.
When you place an outside call the digits you dial are compared with the Digit Conversion
Table. If a match is found, the digits are converted as defined in the table. Within the table
are 32 sub-tables with up to 200 entries of up to sixteen digits for each sub-table for UCP.
